ACCESS Models

ACCESS models are computer programs that represent key components of the Earth's climate system, including the atmosphere, oceans, land surface, and sea ice. These models use complex mathematical equations to simulate past, present, and future weather and climate conditions, as well as idealised scenarios. Different ACCESS models are configured with varying combinations of Earth system components to address specific research needs.
Developed in collaboration with international climate modeling institutions, these models are optimized for Australia’s high-performance computing (HPC) systems and tailored for Australian researchers.

Below is a list of ACCESS models supported by ACCESS-NRI.

ACCESS-CM A global climate model that includes the atmosphere, land, ocean and sea-ice components, and produces physical climate simulations

ACCESS-ESM A global climate model with additional land and ocean biogeochemical components to simulate both the physical climate and global biogeochemical cycles

ACCESS-OM A global coupled ocean and sea ice model used to understand both physical and biogeochemical processes in the ocean.

ACCESS-rAM A high resolution, regional atmosphere model that is an implementation of the UK Met Office Regional Nesting Suite
